Abstract
The invention discloses a hydraulic lifting travelling crane. The hydraulic lifting travelling crane comprises a lifting cylinder and a travelling device, wherein the travelling device comprises a travelling crane frame and travelling wheels, the travelling crane frame is provided with a slide groove, the lifting cylinder is provided with an installation flange which is clamped in the slide groove and can move along the length direction of the slide groove, a horizontal cylinder is arranged at one side of the travelling device, the piston rod of the horizontal cylinder is hinged with the lifting cylinder, the horizontal cylinder and the lifting cylinder are connected with a manual reversing hydraulic system through pipelines, and when the manual reversing hydraulic system works, the lifting cylinder acts, the piston rod of the lifting cylinder stretches and withdraws so as to lift up or lay down heavy objects; the horizontal cylinder acts, the piston rod of the horizontal cylinder stretches and withdraws so as to push or pull the lifting cylinder, so that the lifting cylinder slides in the slide groove through the installation flange so as to horizontally reciprocate on the travelling crane frame. The lifting travelling crane can effectively prevent generation of electric spark, and is widely used in a coal mine, a gasoline station, a gas station and the like where combustible gas exists.
Description
Technical field
The present invention relates to hydraulic efficiency equipment manufacturing technology field, relate in particular to a kind of hydraulic hoisting driving.
Background technology
There is imflammable gas where in China's coal-mine, oil, petrol service station and gas station etc., the inflammable and explosive occasion of serving a ball, the security requirement of these occasions is very high, and these occasions still need to use lifting appliance to be used for a few thing in some specific time.And the lifting appliance that China is used is now mostly electric hoisting equipment, electric hoisting equipment easily produces electro spark in the course of the work, may cause blast and the burning of imflammable gas, therefore, electric hoisting equipment be used in these inflammable and explosive occasions be breakneck, be very unaccommodated.
Summary of the invention
The object of the invention is the defect for above-mentioned prior art, a kind of hydraulic hoisting driving is provided, energy actv. is avoided the generation of electro spark, and it can be applied in colliery, oil, petrol service station and gas station etc. widely the place of imflammable gas.
To achieve these goals, technical scheme of the present invention is:
A kind of hydraulic hoisting driving, comprise lift cylinder and running gear, described running gear, comprise driving frame and the road wheel that is arranged on driving frame bottom, described driving frame is provided with sliding tray, described lift cylinder is provided with mounting flange, described mounting flange is installed in sliding tray and can moves along the length direction of sliding tray, one side of described running gear is provided with horizontal cylinder, piston rod and the lift cylinder of horizontal cylinder are hinged, described horizontal cylinder, lift cylinder connects manual reverse of direction hydraulic efficiency pressure system by pipeline, in the time of manual reverse of direction hydraulic work system, lift cylinder action, the piston rod of lift cylinder is flexible, can promote in vertical direction or put down weight, horizontal cylinder action, the piston rod of horizontal cylinder is flexible, can promote or pull lift cylinder, makes lift cylinder slip in sliding tray by mounting flange, and lift cylinder horizontal reciprocating on driving frame is moved.
Further, described lift cylinder, horizontal cylinder are multi-stage expansion cylinder.
Further, described manual reverse of direction hydraulic efficiency pressure system, has two Bidirectional manual pumps and two hand change over valves, and two Bidirectional manual pumps are connected with lift cylinder, horizontal cylinder respectively with two hand change over valves.
Compared with prior art, the invention has the beneficial effects as follows:
Hydraulic hoisting driving of the present invention, promoting telescoping cylinder is mainly lifting heavy, weight can be moved up and down, horizontal extension cylinder is fixed on driving frame, effect is that push-and-pull promotes telescoping cylinder, making to promote telescoping cylinder can level move around on driving frame, the advantage of these two kinds of telescoping cylinders is that the installing space taking is little, but can realize longer stroke, to guarantee that weight has very large removable space in the time of lifting, and can realize larger lifting tonnage, two kinds of telescoping cylinders complete by manual operation system, manual reverse of direction hydraulic efficiency pressure system has two hand change over valves and two Bidirectional manual pumps, two Bidirectional manual pumps and hand change over valve are respectively controlled a kind of telescoping cylinder, non-interference, and can also realize two kinds of telescoping cylinders and carry out work simultaneously.Because manual reverse of direction hydraulic efficiency pressure system is manual work, avoid the danger of the caused generation electro spark of electric operating.Under driving frame, there is rail wheel, can realize driving and move around in orbit.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Fig. 3 is that the A-A of Fig. 1 analyses and observe structure for amplifying schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further described.
As Fig. 1, shown in 2 and 3, hydraulic hoisting driving of the present invention, comprise lift cylinder 1 and running gear, described running gear, comprise driving frame 2 and the road wheel 3 that is arranged on driving frame 2 bottoms, described driving frame 2 is provided with sliding tray 4, described lift cylinder 1 is provided with mounting flange, described mounting flange is installed in sliding tray 4 and can moves along the length direction of sliding tray 4, one side of described running gear is provided with horizontal cylinder 5, the piston rod of horizontal cylinder 5 and lift cylinder 1 are hinged, described horizontal cylinder 5, lift cylinder 1 connects manual reverse of direction hydraulic efficiency pressure system 6 by pipeline, in the time that manual reverse of direction hydraulic efficiency pressure system 6 is worked, lift cylinder 1 is moved, the piston rod of lift cylinder 1 is flexible, can promote in vertical direction or put down weight, horizontal cylinder 5 is moved, and the piston rod of horizontal cylinder 5 is flexible, can promote or pull lift cylinder 1, makes lift cylinder 1 slip in sliding tray 4 by mounting flange, and lift cylinder 1 horizontal reciprocating on driving frame 2 is moved.
Described lift cylinder 1, horizontal cylinder 5 are multi-stage expansion cylinder.
Described manual reverse of direction hydraulic efficiency pressure system 6 has two Bidirectional manual pumps 7 and 8, two Bidirectional manual pumps 7 of two hand change over valves to be connected with lift cylinder 1, horizontal cylinder 5 respectively with two hand change over valves 8.
The above is only one embodiment of the present invention, it should be pointed out that for those skilled in the art, not departing under the prerequisite of the technology of the present invention principle, can also make some improvement, and these improve and also should be considered as protection scope of the present invention.
